8 Claims.

.The present invention relates to improvements in a roll film container and, more particularly, to details of construction for such a container.

Many forms of containers for enclosing film o rolls are known to the prior art; However', previous film containers have either beencomplicated in construction or difficult to assemble.' Furthermore, some of the prior art containers could not be opened for removal of the lm roll without destroying some part of it.

The primary object of the present invention is the provision of a container for roll film which is simple, but rugged, in construction and which may be readily assembled or dismantled without l destruction of any of the component parts.

Another object of the invention is the provision'of a iilm container comprising a body por-l tion and end caps, and including interengaging connections between the end caps and body portion and which are moved into engagement by the positioning of the end caps upon the body portion. For this purpose, the end caps are each provided with a circular groove having an inclined wall for engaging the edge or rim of the bodyportion to spring the same upon location of the end caps.

Other and further objects of the invention will occur to those skilled in the art during the following disclosure.

The above and other objects of the invention flanges for overlapping the margins of the body` portion and for constraining the body portion in a compressed position. Interengaging connections between the end caps and/body portion are moved into engagement by cooperation between the inclined wall of a groove in each end cap and the end rim of the body portion.V

Reference'is hereby made `to ,the accompanying drawings wherein similar -referencev characters designate similar elements and wherein:

Fig. 1 is a perspective view of the assembled film container according to the invention. Y Fig. 2 is a transverse cross-'section through the body portion of the film container.

Fig. 3 is a fragmentary longitudinal cross-sec# tion through the end cap and margin of the body portion during assembly. l

Fig. 4 is also a fragmentary longitudinal crosssection through the end cap 'and margin of the Abody portion after assembly has been completed.

the slot are separated,

(ci. zoe-5 z) Fig. 5 is a side elevation in partial section of the film spool to beinserted within the film container of the invention.

As previously indicated, the lm container includes a, body portion I0. Said body portion I0 is composed of resilient material and is provided with a longitudinal slot forming a film passage. Such a longitudinal slot may be formed by integral lips ll and I2 of the body portion I0. The body portion I0 -is preferably cylindrical and lips i I and l2 are deformed or bent, in a known manner, to form a passage which extends from the interior of the body portion I0. The lips Il and I2 and. adjacent areas of the body `portion I0 are lined with sections I3 of light sealing4 material, such as plush. A beaded rim M is formed around each edge of the body portion I0.

In dismantled lcondition of the film container,

. the body portion I0 being of resilient material normally assumes a position with the lips II and 20 I2 separated, as illustrated in Fig. 2. For assembly of the film container, the body portion is compressed and constrained in this compressed position by a pair of end caps.

lapping the margins of the body portion I0. A portion I1 of the flange I6 is bent out of the. cylindrical formation of said flange i6 and formsy in the flange a notch through which the lips l I and I2 of the body portion lll may extend. An 30 .overlapping portion' I8 is formed integrally with the portion I1 on the end cap I5. Said overlapping portion I seals the end edges of the film passage formed by the lips I I and I2 on the body portion II).

The end cap I5 also yincludes an end wall I9 which is provided with a groove 2|). The groove 2l! has an inclined wall 2 I. which cooperates with the beaded rim I4 of body portion IIr to expand the same in a manner to be more fully explained hereinafter. Another ,end cap 22 is fitted onto the body portion I0 at the other end and includes a 'fiange 23 for overlapping the margins of the body portion Ill and includes a portion lips II and I2 for formation of the film passage. The second end cap 22. is very similar to endcap I5, except that it is modified for insertion o n the opposite end of the body portion I0.

Interengaging connections are` provided between the body portion and the end caps I5 and 22. Such interengaging connections are preferably of the type that will become engaged upon expansionv of the ends or beaded rim I4 4of the body portion I0.

ufI l,

The end cap I5 includes a ange I6 for over- 25 adjacent to the 45 These connections may be of the manner disclosed. A plurality of protuberances 25 are provided upon the body portion I0 and may be deformed from the material of the body portion I0. A plurality of holes 26 are provided in-the-fianges I6 and 23 of respective end caps I5 and 22. The protuberances 25 and holes 26 are so dimensioned and located that in assembled position of the end caps I5 and 22 on the body portion Il), the protuberances 25 fit into to the body portion.

'I'he end caps I5 and 22 are fitted onto the body portion I in the following manner. The body portion I 0 is first compressed so that the plush sections I3 on lips II and l2 are pressed against each other. This compression of the body portion I0 makes it small enough to fit within the flange I 6 of end cap I5, which is moved axially along the body portion Il! to spring the protuberance 25 into hole 26. As a practicalmatter, the resiliency of the body portion I0 is not large and it is necessary to provide some auxiliary means for insuring the interengagement of protuberances 25 and holes 26. Such auxiliary means to expand the body portion I0 is provided by the inclined wall 2I of the groove 20 in end cap I5.

'I'he relative position of parts during positioning of the end cap I is illustrated in Fig. 3. Continued axial movement of the end cap I5 with respect to body portion I Il, brings the beaded rim I4 into engagement with the inclined wall 2| of the groove 20. Additional axial movement of `the end cap will cause the beaded rim I4 to slide along the inclined wall 2|, to expand this beaded rim Il or margin of the body portion l0. In this manner the margins of the body portion I0 may be flexed so that when protuberances' 25 arrived opposite the holes 26, said protuberances snap into the said holes 26. Without such auxiliary arrangement the assembling ofthe film containers is more difficult and lproper attachment of the end caps to the body portion is les's certain.

'Ihe film to be enclosed by the film container is preferably supplied upon a spool of the type shown in Fig. 5. The spool comprises a core 21 which has portions 28, 29'and 30 of reduced diameter. Portion 28 "receives the disk 3| and forms a. journal for one end of the film spool in the end cap l5, as shown in Fig. 1. Portion 30 receives the disk 32 and is also journaled in endof soft wood. A pin 35 extends through the core 21. The film spool is journaled in the end caps I5 and 22 and may be rotated by grasping the reduced portion 28-oi the core 21 which extends to the exterior of the f llm container.

The film container just disclosed is outstanding in simplicity of construction and easy to assemble. lOther modifications of the film container will be obvious to those skilled in the art, but the scope of the invention is not to be judged by the present illustrations, but rather by the appended claims.
